There is a LaTeX-based manual for the Fluksometer, which is "just a bit" outdated, there are blog posts by Bart, and there are a lot of forum threads on diverse topics, dealing with certain details on different questions and requests.
Complaints have been raised that this diversity is rather not too convenient, even though G**gle search is pretty easy to adapt, if you dare to ask the right question...
So, how to overcome this situation?
Bart proposes to open a GitBook; I rather would keep it much simpler and transfered the existing manual plus some additons into "markdown", providing a FLM manual wiki, which lives along the source code of the Fluksometer.
Yet to be clarified is the distribution of topics: Is it a chapter-by-chapter book or is it a quick-introduction with accompanying questions and answers, which again raises the "right question" issue, is it an expert compendium or a "Fluksometer for Dummies", explaining also the most simple things?
Make up your mind. What is it, what is required? What is a convenient format to present it? And what would be a format you would be thrilled to contribute?
In the advent of the FLM03E (never trust an 'A'-version ;-)) this is a rather important issue, isn't it?
